Jet Boats Ski Boats
Sales price per unit $10,000 $24,000
Variable cost per unit $4,800 $18,000
Contribution margin per unit $5,200 $6,000

Weighted contribution = ($5,200 x 5 jet boats) + ($6,000 x 2 ski boats) = $26,000 + $12,000 = $38,000
Weights = 5 jet boats + 2 ski boats = 7 boats
Weighted-average contribution margin per unit = $38,000 / 7 boats = $5,428.57 per boat

Required sales in units = (Fixed costs + Target profit) / Contribution margin per unit
Required sales in units = ($300,000 + 0 ) / $5,428.57 per boat = 55 boats

55 boats in the ratio of 5:2 are 39 jet boats and 16 ski boats.
